Research Of Greenhouse Temperature And Humidity Auto-control System

With the continuous development of the microprocessor technology and industry automation level, the microprocessor fuzzy-control technology has been widely spreaded and applied.This control technology was based on fuzzy-control theory and provided a kind of fire-new and efficial control method in application of industry control, household appliances and instrument intelligence, it has prodigious practical use and prospect.In this paper, according to the character of environment control in greenhouse, we applied fuzzy-control theory to realize auto-control to temperature and humidity. We complished finally the software and hardware design of the whole control system.In the first chapter, the paper introduced simply the development condition of auto-control system in greenhouse, and put forward the research subject. In the second chapter, the paper applied fuzzy control theory, the fuzzy controller for temperature and humidity composition were designed realized. In the third chapter, this paper introduced hardware design of system. In the fourth chapter, the paper introduced software design of system. Finally, several pieces of suggestions were put to improve the whole system.
